My San Diego site is about 300ft elevation and Descanso is about 3500ft higher. When I left Descanso yesterday afternoon, the temperature was a sunny 90F and when I neared San Diego the temperature was a cloudy 60F for the last 10 miles (yeah I know not sunny but even in SoCal you get some "weather*"). My old hands were hurting by the time I took my thin elkskin gauntlets off (I haven't connected heated grips power yet).
My alternatives are a windshield (that's an acceptable appearance for the BMW but not the RE from my perspective) or multiple glove sets (yeah right I'm going to pull over and switch). Plus I really like the warmth coming through my hands. You have a buy a high-end La-Z-Boy to get this combination of heating and vibration.
The reason I haven't connected power is I was waiting on a seat decision. My current solo seat was modified with a gel pad by the previous owner. I don't know if it works but I tend to slide off the seat. I bought a used Lycett that the previous owner said he mounted on his RE but I can't see how. I've asked Tim (Parts Man) about a BiltWell (springs, not much padding) vs Low seat (no springs, 50% stock padding). In my experience the springs are for looks not comfort. I'm concerned about not being able to shift my position on the Low seat so I'm waiting for Bmadd34 to report on his long ride experiences. And I intend to centrally locate some electronics under the seat (fuse block, ignition booster, etc) which also affects my decision.
WRT electronics location, I can easily distribute the separate functions throughout the motorcycle (I've already started: the hazard flasher/HelpMe/turn signal electronics are in the "doghouse" tail piece). So a Low seat is still an option.
My long-winded point is I'm carefully modifying the RE to my safety, comfort, capability and reliability needs while retaining its traditional appearance that emphasizes that single cylinder "thumper" engine. You saw Triumph spend time and money making their fuel injection look like traditional Amal carburetors. I think RE did much better in their modernization and I don't want to give that up. For instance, my mirror saga which I'll post shortly: six in three months.

http://mapq.st/2MlaJ4O. I ride it as a track day in that I strive for consistency in my line, braking points, etc while keeping to the 55mph speed limit (60mph indicated). So getting the ergonomics correct on this motorcycle are essential to allowing me to focus on the road.
*SoCal weather: in spite of paying high taxes and contrary to visitor temperature expectations, our coast can be cold in the summer and hot in the winter and vice versa in our mountains.
